Fluency Is Speed Plus Accuracy
Knowing 7 × 8 and knowing it instantlyare different skills — and the instant kind is what frees working memory for long division, fractions, and algebra later. Timed tests measure exactly that. This one keeps the classic format teachers use (mixed facts, running clock) but adds what paper can't: the moment you finish, it knows which facts cost you, and one click builds a drill from precisely those. Three or four short rounds beat one long grind — end on the missed-facts drill and the next full test almost always scores higher.
